1 = -3y +2z
-5 = 3x - z
3 = -2x +y

I know through a wrong mathematical calculation that x = -4/3,  y = 1/3, and z = 1, however, I can't seem to put these equations together and isolate the variables. Everytime I try to isolate the variables I end up cancelling the whole thing out and end up with 0=0 which is decent if you are looking for a check, but totally not useful for solving for unknown variables.

Can anyone show the steps on how the variables are isolated and derived?
